Has anyone tried these?
http://cgi.audiogon.com/cgi-bin/cl.pl?ddaccstwek&1060666174A friend & myself each gave them a shot for $20 for a set of 4 sheets 2" wide x 6.75" long. My friend placed them in his lower end DVD player, on the chassis and on the inside of the top cover. I placed them inside the cover of my Sony 999ES DVD player, and on the underside of the chassis.
My friend had excellent results, and compaired the difference in sound as if one would upgrade to high quality speaker cables from monster. I also liked the tweak, it seemed to tighten up some of the acoustic notes that the 999 was having trouble reproducing acurately. Please note that I am spliting hairs here as the 999 is excellent for CD reproduction.
We are quite satisfied with the effectiveness of this tweak, but the only thing I want to point out is that I was shopping at Home Depot the other day, and in the roofing section they sell a
VERY similar product. It is a roll of aluminum backed roof joint sealing tape, 2" wide x 16' long for a whopping $8. So for all you that want to try this tweak on all of your gear, without breaking the bank, find the local Depot!
